A: Q235 is cost-effective for general building structures. For high-load or seismic zones, Q345 is recommended due to its superior yield strength and impact resistance. We can assist with material selection based on your design load and environmental conditions.
A: Yes. Asia Metal offers value-added services including CNC plasma cutting, drilling, bending, and beveling. We accept DXF, DWG, or PDF drawings for precision fabrication — reducing your on-site labor and waste.
A: Absolutely. We welcome SGS, BV, TÜV, or customer-appointed inspectors at our facility. All inspection costs and scheduling are coordinated transparently with no delays to your delivery timeline.
A: Plates are bundled with steel straps, protected with waterproof VCI paper, and mounted on fumigated wooden pallets or crates. Corner protectors and desiccants are included for ocean freight. Custom packaging per client request is available.
